No matter whether you want them as a fun toy to play with, an extra measure of security, or an extra edge while hunting, night vision binoculars make for a worthwhile investment. Your first decision when you begin shopping will be whether or not to get a consumer or high end model. While you may get by with a pair of sub-$100 binoculars, the better models go up in price astronomically, with many well over $1,000.
These consumer night vision binoculars are a top budget option, as they sell for $75 at Amazon. They pack a ton of features despite their low price: you'll find real infrared night vision tech, which on this model allows you to see up to 50 feet ahead under total darkness. The EyeClops also feature a double eye LCD display and an adjustable focus. They're also durable enough so that you won't mind letting the kids play with them every once in a while!
These mid-priced binoculars sell for $326 at Overstock. They feature an included IR infrared illuminator, have a lightweight rubberized body that's durable in tough conditions, and use a pulsing frequency that leads to better battery life than comparable models. This model also uses the Yukon Eclipse Lens Cover system, which allow for easier storage and rotation of the lens caps. This may be your best option if you want a very functional model that's a step above the consumer-focused designs.
If you're getting more serious about your nighttime searching, consider this ATN model. Available from B&H Photo for $539, the Night Cougar is a headlamp style binocular with two intensifier tubes and two objective lenses. The binoculars are extremely lightweight and have a built-in infrared illuminator, multicoated all-glass optics, and a Proshield lens for unparalleled quality.
